x86: fix crash due to missing debugctlmsr on AMD K6-3
currently if you use PTRACE_SINGLEBLOCK on AMD K6-3 (i586) it will crash. Kernel now wrongly assumes existing DEBUGCTLMSR MSR register there. Removed the assumption also for some other non-K6 CPUs but I am not sure there (but it can only bring small inefficiency there if my assumption is wrong). Based on info from Roland McGrath, Chuck Ebbert and Mikulas Patocka.
